What does the '+0.50mm' size mean for these bearings?

The '+0.50mm' indicates that these bearings are oversize. They are intended for use when the crankshaft journals have been machined down by 0.50mm during an engine rebuild. This ensures proper fit and oil clearance on a reconditioned crankshaft.

Are these bearings suitable for a daily driver or only for racing?

These bearings are part of King Engine Bearings' pMax Black racing line, which means they are built for higher performance and load capacity. While they can be used in a daily driver, they offer improved durability and performance, especially if the engine has been modified or is subject to harder use.

What is the difference between these pMax Black bearings and standard bearings?

The pMax Black series bearings utilize a tri-metal construction, which offers superior strength and wear resistance compared to standard bearings. This advanced material composition helps them withstand higher loads and temperatures, making them a more robust option for engine builds.
